Abstract

Connecting pieces (100) for fluidically coupling medical devices and/or medical lines, which are specified in various standards and are designed for coupling to a correspondingly designed counter connecting piece (100), are known. Connecting pieces (100) of this type have a fluid channel, surrounded by a line portion (110), for coupling to the counter connecting piece (100) in a plugging direction (2) in a peripherally leak-tight manner and for subsequently exchanging liquids and/or gasses with the counter connecting piece. According to the invention, a connecting piece according to the invention has a transfer apparatus (200, 300) for data transfer and/or for transferring electrical energy with the counter connecting piece. A connecting piece (100) of this type is preferably used in an intelligent medical fluid conduction and transfer system, in which various components are interconnected by means of the connecting pieces not only fluidically but also for the purpose of transferring energy and/or data with each other, such that, for example, information regarding the medication can be exchanged or validated.

Description

Intelligent medical fluid conduction and transfer system and components therefor

AREA OF APPLICATION AND STATE OF THE ART

The invention relates to a medical fluid conduction and transfer system as well as components which can be used in such a system.

A medical fluid guidance and transfer system is a system for guiding fluids in connection with the medical treatment of a person or an animal. Such a system can, for example, be an infusion system or a transfusion system or a dialysis system or a system for extracorporeal gas exchange or an extracorporeal circulatory support system or a heart-lung machine or a nutritional system or a drainage system for body fluids, such as urine, wound secretion or intestinal contents or a ventilation system be.

A generic as well as a fluid conduction and transfer system according to the invention usually has at least one fluid source for providing a medically relevant fluid or fluid mixture, an access unit for applying the medically relevant fluid or fluid mixture in a patient, and a connecting line system that provides the The fluid source and the access unit connects and is designed to conduct and transfer the medically relevant fluid mixture from the fluid source to the patient, the connection conductor system usually having at least one regulating transfer element.

A fluid or fluid mixture within the meaning of the invention can be gaseous, e.g. B. breathing air, ambient air enriched with anesthetic gas, oxygen; or it can be liquid, e.g. B. an infusion solution, a drug, urine, blood, a dialysate or precursors of the dialysate.

A fluid source is understood to be a storage unit or a media supply for the fluid or fluid mixture, for example wall connections for oxygen or natural sources.

An access unit can be formed, for example, by a needle or a temporary vascular access - such as a central venous catheter or an arterial access - which is introduced into a vein or artery of the patient. An access unit can also be formed by a port, ie a subcutaneously implanted catheter system which can be punctured from the outside and offers permanent access to the arterial or venous vasculature or to certain body cavities. The connecting conductor system in the sense of the invention combines all components of the fluid conduction and transfer system that are necessary for conveying and transferring or distributing the medically relevant fluid or fluid mixture. A regulating transfer element such as, for example, a three-way cock, a cock bank or a filter element is part of the connecting conductor system within the meaning of the invention. A transfer element is understood to mean an element that serves to simultaneously convey or transfer medically relevant fluids or fluid mixtures from several fluid sources connected to the transfer element via a connecting conductor of the connecting conductor system to an access unit on the patient.

Practically every inpatient receives an access unit - i. H. Intravenous (IV) peripheral indwelling cannulas, central temporary indwelling catheters or permanently implanted vascular accesses (so-called "ports") - drugs, chemotherapy, infusion fluids or nutritional solutions are administered. This is also referred to as IV therapies. Almost all of these therapies are already used today offline programmable pumps - e.g. infusion pumps in infusion systems - carried out, ie the pump parameters are preset according to their use on the patient and linked to the patient.

For patients in intensive care units, under anesthesia or with severe illness, a large number of IV therapies are often carried out simultaneously via different IV accesses. The number can be up to 30. In these situations, several parallel intravenous accesses are necessary in order to apply precisely controllable life-sustaining and mutually incompatible drugs in a controlled manner. The correct administration and documentation of these therapies is highly relevant for patient safety and the medico-legal situation of the treating nurses, doctors and facilities. Billions of single-use items are manufactured annually to carry out these therapies.

Today's infusion and connection systems were devised at the end of the 19th century and are particularly geared towards good functionality in pure gravity operation. The movement of the infusion liquid can also be realized by means of an infusion pump or by active liquid outflow from the fluid source - for example from a storage container for the infusion liquid. On the way to the access unit, e.g. B. an IV access on the patient, one or more regulating transfer elements can be formed. The Luer system, which is almost exclusively used internationally for IV therapies, goes back to the instrument maker Hermann Wülfing Luer (T 1883). The combination of the Luer connection with a rotation lock (Luer-Lock, as a further development of the Luer-Slip plug connection) was introduced for the first time Described in 1952. The system is internationally standardized in the ISO standard ISO 80369-7. In its current form, the components of the infusion system or a fluid conduction and transfer system are manually plugged together or screwed and manually checked for their physically correct connection.

The infusion fluids are transported from a storage container to an IV access on the patient via a connecting conductor system, which is formed by the infusion lines or hoses in an infusion system, the infusion pump and the regulating transfer elements.

For a functional and medically effective fluid conduction and transfer system, it is essential that all components function correctly and are connected to one another. In the case of an infusion system, for example, it must be ensured that the correct medication is administered via an appropriate infusion pump at the correct infusion rate and a connection through to the patient based on common compatibility and safety criteria must be ensured so that, for example, incompatible medication and Infusion solutions cannot be administered together. With the infusion systems known up to now, the correct connection is checked manually by the doctor or a nurse.

For the safe functioning of a medical fluid control system, it is essential to observe the hygiene standards to protect the patient. This applies in particular to the correct use of filters, avoiding unnecessary reconnections and adhering to the change intervals. Fluid control systems known to date do not allow testing or monitoring of these parameters. Instead, the control and documentation is carried out manually by the doctor or a nurse.

Medical fluid control systems can pose a considerable risk to fellow patients, relatives or caregivers. This is the case, for example, when the fluid control system is filled with highly toxic substances, such as in chemotherapy, and these substances escape due to leaks or operating errors. The leakage of chemotherapeutic agents cannot be recognized by previous systems.

Furthermore, a therapy documentation, integrity check, plausibility test or feedback on the status and prob lems in the context of z. B. infusion therapy not possible. Patient safety suffers from these restrictions and there is a lot of manual documentation required. An electronic gearing z. B. infusion therapy with the other therapy sequences is not possible. TASK AND SOLUTION

The object of the invention is to provide a fluid conduction and transfer system which does not have the deficits mentioned or only to a lesser extent and also preferably meets the following functional requirements: 1. The fluid conduction and transfer system should ideally have its integrity different from the Independently validate the fluid source, i.e. from the medication container, infusion bag, medication bottle or the like up to the patient, recognize incorrect connections and medication incompatibilities and document the therapy in a validated manner. Validation should be understood here to mean that a drug has not only passed through the infusion pump, for example, but has also entered an IV catheter. 2. IV therapy as ubiquitous and resource-intensive therapy as well as the use of transfusion systems, dialysis systems, feeding systems, drainage systems, heart-lung machines, extracorporeal circulatory support systems, systems for extracorporeal gas exchange or ventilation systems should be integrated into modern, electronic work processes incorporate. I.e. The expected end of therapy, necessary syringe changes, nutritional solution changes, drainage changes, etc. must be reported and requested independently by the fluid conduction and transfer system. 3. The fluid conduction and transfer system must be robust enough that system testing can, for example, allow home infusion and chemotherapy to be carried out.

A further object of the invention is to provide suitable components for such a fluid conduction and transfer system.

The object of the invention is primarily achieved by a connector for the fluidic coupling of medical devices and / or medical lines.

A connector in the sense of the invention is a coupling device at the end of a fluid line or as an input or output of a medical device, which can be mechanically coupled with an opposing counter connector or with an identical connector in order to put the connectors in a position for fluid exchange. The invention relates to be special connectors from the field of medicine, which are specified in more detail below on the underlying standard. Connection pieces according to the invention can be coupled with standard-compliant counter-connection pieces to form a fluid connection.

Specifically, the invention relates to the following connectors: Connectors according to the ISO 80369 family of standards, in particular connectors for intravascular or hypodermic applications ISO 80369-7, connectors for enteral applications according to ISO 80369-3 and connectors for neuroaxial applications according to ISO 80369-6,

Stopper (for an infusion bottle in accordance with ISO 8536-2, crimp caps for an infusion bottle in accordance with ISO 8536-3 and piercing parts in accordance with ISO 8536-4 for connection to an infusion bottle or a bag, subcutaneously implanted ports in accordance with ISO 10555-6 and punch-free cannula for coupling to such an implanted port in accordance with ISO 10555-6, conical connectors for anesthesia and ventilation devices in accordance with ISO 5356-1 and connectors in accordance with ISO 5367,

Connection pieces for the internal connection of a dialysis system as a port for the dialysis fluid according to ISO 8637-1 (Section 4.4.4, Figure 2 of the ISO standard).

The standard information relates to the standards applicable in July 2020.

A connection piece according to the invention allows the respective connection pieces to create a fluid coupling between the connection pieces in the usual manner. For this purpose, a connection piece according to the invention has a fluid channel surrounded by a line section for circumferentially tight coupling in a plug-in direction to the mating connector for the subsequent exchange of liquids and / or gases with the mating connector. Connection pieces according to the invention are compatible with standard connection pieces that are not designed according to the invention with respect to the liquid line. A particularly common and preferred form of fluid coupling provides that conical line sections are provided on both sides of the connection piece and the mating connection piece, which are pushed into one another during the coupling and hold in a clamping manner.

In addition to the line section, a connector according to the invention has a transmission device for data transmission and / or for the transmission of electrical energy with the mating connector. Although in principle separate transmission devices for data and electrical energy are possible, it is preferably a combined transmission device for data transmission and / or for the transmission of electrical energy. Any transmission devices explained in the context of this application are to be understood in such a way that it can also be a combined transmission device or a separate transmission device for electrical energy or data.

A connection piece according to the invention allows, through its transmission device, to establish connections between individual components in the context of the fluid control and transfer systems mentioned, through which not only a fluid exchange can take place, but also electrical power and / or digital data can also be exchanged between the connection pieces nen.

The need for the transmission of electrical energy or electrical data exists in particular in order to supply loads that follow the connector in the fluid path with energy. However, it can also be a power conduction function from a connector to a second connector provided at the other end of a fluid line.

Data transmission at the connection piece can serve the purpose of exchanging information, in particular to check the topology, to exchange sensor data and, if necessary, to compare it, or to take on other control functions or information acquisition functions. A very simple application is given when the data is transmitted in order to read out production data from the connector, such as the production batch or an expiration date. A very simple application is also given when a connector is designed to transmit information about the permissible use of the connector to a mating connector, so that incorrect connections can be detected.

The transmission device can be designed in different ways, as will be explained below. However, it is designed in such a way that a coupling process with regard to the Fluid channels of the connector and of the mating connector simultaneously also leads to the coupling of the data and / or energy transmission device.

Connection pieces according to the invention in medical technology are usually designed predominantly as plastic parts that may comply with the limitations of the respective standards. The transmission device preferably comprises metallic or polymeric conductors which, in particular, are preferably embedded in the plastic of the connection piece. However, designs are also possible in which the conductors or contact surfaces connected to them are attached to the outside of the connection pieces.

The connector preferably has a transmission device for data transmission and / or for the transmission of electrical energy, which is provided on the connector in such a way that it can exchange data or supply energy with a corresponding transmission device on the mating connector.

It is preferred here if the transmission device of the connector is designed with at least one coil for inductive coupling with the transmission device of the mating connector.

Inductive transmission provides that signals are transmitted between two coupled connectors using electromagnetic induction. Corresponding systems are known, in particular through RFID tags and through the Ql standard of the Wireless Power Consortium for energy transmission. The inductive data transmission and energy transmission are comparatively position tolerant. This is particularly advantageous in systems which, due to their design, for example due to a steep conical design of the coupling elements, cannot guarantee a defined end position of the connecting pieces.

With a defined relative arrangement of the coils to one another, electromagnetic induction has a practical efficiency of over 50%. An efficiency of 80% can also be achieved. This means that even with a serial arrangement of 5 pairs of connectors, around 30% of the power is retained.

The coils required for the inductive coupling are preferably securely separated from the fluid, in particular by being provided in an isolated cavity of the connection piece. It is particularly preferred if the coils are surrounded by a one-piece plastic part, which is preferably produced by an injection molding process with the coil inserted. There is no alternative to inductive transmission. The transmission device of the connection piece can also be designed with an electrode element for capacitive coupling with the transmission device of the counter-connection piece and an electrode element there.

In principle, capacitive energy and data transmission is considered less tolerant with regard to positional deviations than inductive energy and data transmission. Since, however, in connection pieces according to the invention, depending on the type, the relative position of two coupled connection pieces is known very precisely, the capacitive coupling can also be a viable option in the present application.

Furthermore, it can also be provided that the transmission device of the connection piece is designed with at least one conductive contact surface or with at least one conductive and preferably resilient contact element for galvanic coupling with the transmission device of the mating connection piece. Preferably, two contact surfaces or two contact elements are provided on the connection piece.

This means that at least one exposed contact surface or contact surface that can be exposed by the coupling process, in particular a metallic contact surface, is provided on the connection piece, which comes into contact with a correspondingly provided contact surface of the mating connection piece during the coupling process of connection pieces. One side is preferably formed by a resilient contact element in order to enable a position-tolerant coupling. The galvanic coupling is usually viewed as disadvantageous in practice, since the exposed contact surfaces can easily become dirty and the risk of an unreliable data coupling is comparatively great. In addition, there is the problem of non-inert surfaces, which can be attacked by drugs and which can lead to biocompatibility problems. The advantages of galvanic coupling, however, are its simplicity and the almost 100% very high efficiency of energy transfer between the connectors.

The integration of the transmission device in the connection pieces takes place in such a way that when two connection pieces are coupled, the energy transmission or the data transmission is possible without interference. One possible construction provides that the transmission device has at least one planar coil, at least one planar electrode element and / or at least one planar, conductive contact surface. Such a planar element is understood to mean an element which is at least three times as large transversely to the direction of insertion as in the direction of insertion. Such a planar element can be arranged in particular on or in a circumferential collar, which is preferably made of plastic and / or is formed in one piece with the bearing section mentioned. In the course of the coupling, this circumferential collar is brought closer to another circumferential collar of the counter-connector until the coil, the electrode element or the conductive contact surface are sufficiently close to allow data transmission between the opposing elements.

The planar element is therefore preferably designed as an element surrounding the bearing section. In the case of a coil, it is preferably designed in a spiral shape, that is to say with a variable diameter. In the case of an electrode element for capacitive data or energy transmission and in the case of a contact surface for galvanic coupling, a disk-like shape is preferably given which has a central hole through which the fluid channel runs. In particular, in the case of a disk-shaped electrode element or a disk-shaped contact surface, two such elements can be provided, which are concentric and have different diameters in order to enable two pole connections or bidirectional data transmission.

However, a design deviating from the planar design is preferred, namely one in which the transmission device has a helical coil surrounding the fluid channel, at least one annular or sleeve-shaped electrode element surrounding the fluid channel or at least one conductive contact surface surrounding the fluid channel in an annular or sleeve-like manner. An annular surface is understood to mean a surface whose normal vector encloses an angle of <30 ° with a radial direction. An inclination deviating from a pure ring surface or sleeve surface with a radial angle of 0 ° can result in particular if the element is oriented following the wall of a coupling cone.

With this type of design, a relevant or even primary extension of the elements in the plug-in direction is provided. In the case of a coil, this preferably has a cylindrical or conical shape, at least in sections, which extends along the fluid channel. In the case of an annular or sleeve-shaped contact surface or an annular or sleeve-shaped electrode element, this or this has the shape defined above, two corresponding elements being provided offset from one another in the plugging direction. A transmission device of this type is preferably attached by the connection piece being provided with a sleeve-shaped ring section on the inside, outside or inside of which the helical coil, the ring-shaped electrode element or the ring-shaped conductive contact surface is provided.

This sleeve-shaped ring section is preferably formed in one piece with the line section. It can therefore be formed, for example, by a circumferential wall separated from the line section by an intermediate space. This can, for example, also represent a coupling section, on the inside or on the outside of which a coupling device is provided for mechanical coupling with the counter-connector, in particular an internal thread, an external thread, a bayonet slot or a bayonet cam for engaging a bayonet slot.

In particular, however, it can also be provided that the ring section and the line section are at least partially identical. The walls that directly limit the fluid channel are in this case also carriers of the elements provided for the transmission. In particular, depending on the type of connection piece, it can be a section-wise conical wall that enables the tight liquid coupling. Especially in connection pieces with such at least partially conical walls, the end position of coupled connection pieces is comparatively indeterminate, so that the transmission device in the sleeve-shaped ring section can be advantageous compared to a circumferential collar in the planar design due to the reproducible spacing and sufficiently long coils in the plug-in direction. In the case of a wall which is conical at least in sections and in which a coil is provided, this can likewise be correspondingly conical or else cylindrical. The conical design is preferred.

The use of the line section as a ring section that carries or surrounds the transmission device is sometimes advantageous compared to the use of a separate sleeve-shaped Kopplungsab section for accommodating the transmission device, since a rotatable coupling section, for example in the form of a union nut, can be used as a rotatable element could only be connected to a head of a fluid line with additional effort.

The connection piece is preferably made at least partially from plastic, in particular the said line section, the circumferential collar or the sleeve-shaped ring section may be made of plastic. In each case, preference is given to those plastics that can be found in the named standards as recommendations or specifications.

In principle, designs are possible in which an electrical consumer or an integrated circuit is directly connected to the transmission device, without any further transmission of energy or data beyond the consumer or the integrated circuit. Usually, however, it is provided that lines are provided in the connection piece in the connection piece and in particular for the purpose of forwarding electrical energy or data. These are preferably metallic or polymeric conductors.

In the case of a connector according to the invention, at least one output device can be provided, preferably in the form of an optical output device such as an LED. Such an output device can signal the status of the connector directly on site. An example of this is the possibility that the output device uses lights or the specific luminous color to indicate whether the connection piece has been connected correctly. For example, in the case of a longer line made up of several sections, it could be quickly recognized whether all connection pieces are correctly connected. If this is not the case, this can be recognized by the fact that the corresponding LED is not lit or by means of a corresponding signal color.

Furthermore, it is preferably provided in a connector according to the invention that at least one integrated circuit is included. This can be inte grated in particular in a connector. The integrated circuit is connected to the transmission device of a connector in order to receive data or electrical energy.

In a particularly simple case, the integrated circuit can only or primarily take over communication tasks, in particular communication with the data transmission devices of two connection pieces. However, it can also take on more complex functions and in particular to include digital or analog outputs or inputs. The inputs can in particular be connected to a sensor system integrated into the connector or the fluid line, for example a sensor system for detecting the coupling state of the connector or a sensor system for detecting a property of the flowing fluid or its volume flow. The outputs can be used to control actuators, the aforementioned output device, in particular in the form of an LED, also being an actuator in this sense. The invention also relates to a set of at least two connecting pieces of the type described, which are designed according to one of the aforementioned systems for mechanical coupling to one another, ie are usually male and female. The two connection pieces are designed in such a way that their respective fluid channels are brought into communicating connection with one another through the mechanical coupling, and their respective transmission devices are brought into a position relative to one another that enables data transmission or transmission of electrical energy.

Such a set according to the invention usually does not have the two insulated connection pieces, but rather two connection pieces which are each part of a medical fluid line or a medical device.

The invention also relates to a medical fluid line for transporting liquids. This fluid line has a line body with an elongated shape, which is traversed by a fluid channel for the fluid or fluid mixture. This can in particular be a rigid tubular body or a flexible hose body. At least at a proximal end of the line body, but preferably both at a proximal and an opposite distal end of the line body, a connector of the type described above is provided so that the channel of the line body communicates with the fluid channel of the connector or the connectors stands. In addition, designs of a fluid line that has more than two ends are also conceivable, for example a fluid line with a Y-configuration. In such a case, corresponding connection pieces are preferably provided at all ends of the fluid line.

If the fluid line is provided with at least two connection pieces, these can be identical or be designed in opposite directions in the manner of a male and a female connection piece.

An electrically conductive conductor for conducting digital data and / or for conducting electrical energy is preferably also provided along the line body with the fluid channel provided therein. Various designs are conceivable here. In the simplest case, the lead body and the conductor can only run parallel to one another, but without being connected to one another. It is also possible that the conductor is formed separately from the line body, but is connected to the line body along the extent of the line body by means of coupling elements or a helical wrapping around the line body. As special however, integrated solutions are preferred in which the line body and the line, that is to say the electrically conductive conductor, are firmly connected to one another, so that they can at least not be separated from one another without tools. In particular, the line body and the line can be inserted into a common sheath for this purpose. Alternatively, the electrical line can be inserted into a sheath which directly forms the channel of the line body.

Since a line body designed as a hose body has a very high degree of extensibility, the conductor is preferably designed and / or shaped in such a way that it is not damaged by an expansion or deformation of the line body. This can be achieved, for example, by a polymer conductor. It is also possible to create a kind of reserve through the arrangement of the conductor, which allows the tube body to be elongated using the conductor reserve. The conductor in the area of the hose body is therefore preferably at least 10% longer than the hose body itself, in particular preferably even 50% longer. The conductor can be designed to surround the fluid channel of the hose body, for example, helically. A longer designed conductor is also advantageous if the hose body as part of a peristaltic pump is repeatedly compressed and relaxed as intended. In such a case, however, it is particularly advantageous to design the hose body in sections without a conductor, as will be explained below.

The usual type of production provides that a connection piece according to the invention is used as a discrete connection piece, which is connected to the line body, for example is injected onto it. However, a design is also possible in which the proximal end or the distal end of the line body integrally forms the line section of at least one connection piece. It is accordingly provided that the end of the line body directly forms the line section and that the transmission device is preferably also provided directly on the line body, in particular is integrated in its wall.

Usually it is provided that the coupling of energy and / or the data transmission takes place in the area of a connection piece of the fluid line. It is also possible, however, to provide a fluid line according to the invention with a connection device provided for this purpose in a central region and thus in particular at a distance from the connection pieces provided at the end. This is of particular benefit in connection with the use of a pumping device as the master of a data system, which is described below. Such pump devices are often designed as peristaltic pumps and are intended to insert line bodies for the purpose the liquid delivery can be mechanically deformed from the outside. If at least one connection device is provided in the middle area described, this can be supplied with data and / or electrical energy from the outside after the line body has been inserted.

For this purpose, it is considered particularly advantageous if the at least one connection device for coupling / decoupling electrical energy or data is provided with a carrier extending radially from the lead body in which or on which the actual connection device is provided, e.g. a coil. Such a coil is also preferably arranged eccentrically to the fluid channel, so that it does not surround the fluid channel, but is arranged laterally offset to it. It can thus be used particularly advantageously for energy transmission or data transmission with a counter-coil which is provided for this purpose in the pump device.

While an inductive transmission device is preferably provided in connection pieces according to the invention in order to avoid contact between current-carrying parts and the fluid, it is seen as a plausible possibility in the described connection device in the middle area to provide a galvanic coupling. There are then on the outside of the Schlauchkör pers, in particular on the radially extending carrier described, conductive coupling surfaces are provided, which are in contact with corresponding contact surfaces there after inserting the fluid line in the pump device.

If the hose body of the fluid line is compressed by a pumping device as intended during pumping, this can quickly lead to damage to the conductor along the fluid line. In order to avoid this, a fluid line according to the invention can be formed without a conductor in a partial section in a central region, that is between opposite ends of the fluid line and the connecting pieces there. This section can then be repeatedly compressed without damaging the conductor for the purpose of pumping.

If connection pieces according to the invention with a transmission device are provided at both ends of the fluid line, the fluid line preferably has two connection devices of the type described in the central area, namely on both sides of the subsection provided for pumping. As with a connection piece according to the invention, at least one output device can also be provided in a fluid line according to the invention. Such an output device is preferably provided on a connection piece or on two connection pieces at opposite ends of the fluid line.

Furthermore, it can also be provided in a fluid line according to the invention that at least one integrated circuit is included, which in particular can preferably be integrated into a connection piece of the fluid line. In the case of fluid lines with two or more connection pieces, only one of the connection pieces is preferably provided with an integrated circuit. The other connection pieces are then also connected to this integrated circuit via conductors along the line body. However, designs are also possible in which different connection pieces of a fluid line or also of a medical device can have separate integrated circuits that do not need to be connected to one another for data transmission. For example, it could be provided that two different connectors of a fluid line or a medical device are each designed to transmit an identifier by means of separate integrated circuits, these identifiers allowing a connected counter-connector to recognize whether the coupling of the connectors is allowed or not allowed.

The integrated circuit is connected to the transmission device of a connector in order to receive data or electrical energy. In a particularly simple case, it can only take over communication tasks or primarily, in particular communication with the data transmission devices of two connectors or with components connected to them. However, it can also take on more complex functions and in particular include digital or analog outputs or inputs. The inputs can in particular be connected to a sensor system integrated into the connector or the fluid line, for example a sensor system for detecting the coupling state of the connector or a sensor system for detecting a property of the fluid flowing through or its volume flow. The outputs can be used to control actuators, the named output device, in particular in the form of an LED, also being an actuator in this sense.

The invention further relates to a fluid-carrying medical device which is designed to accept, pass through and / or dispense fluids and, moreover, to accept, pass through and / or output data and / or electrical energy. This device has fiction according to the combined acceptance, transmission and / or delivery of data and / or electrical Energy and fluid on a connector of the design described. In the simplest case, such a device is formed by a simple fluid line of the type described.

In particular, however, this also includes more complex devices which are used for the intermediate storage or provision of liquid or which have at least one actuator for controlling and / or pressurizing the fluid. Such an actuator can for example be an electrically controllable valve or a pump. The actuator can be supplied with energy via the electrical energy supplied by the connector or via a separate power supply. Control data for controlling the device can be supplied from the connector or sent to connected devices via the connector.

A device of the type described can also have at least one sensor, the sensor data of which can preferably be transmitted to other devices via the connector. The energy supply can here also follow the electrical energy supplied by the connector. The sensor can be provided to detect various sizes. A design in which the sensor is designed to detect a property of the fluid, for example the temperature, or to detect the volume flow of the fluid is particularly advantageous. The sensor can, however, also be provided for the detection of environmental parameters on the body or in the body of a patient, for example as a temperature sensor, pressure sensor or sensor for detecting the oxygen saturation. Such a sensor can be part of a catheter introduced into the patient or an implanted port, for example.

The device preferably has at least one integrated circuit which is connected to the connection piece for the purpose of supplying electrical energy or digital data. This integrated circuit can also be operated with energy that is fed from the connector and / or exchange data with other devices via the connector. The integrated circuit is used in particular to structure the electronic communication with adjacent fluid-conducting components according to the invention. The integrated circuit can process the data of the sensor described locally in the device and / or control the actuator described locally. In particular, the integrated circuit can be used to implement a closed control loop in the device using the sensor and the actuator. Furthermore, the integrated circuit is used in particular for communication with external components connected via the connector according to the invention. In most cases, in the case of a device with at least two connection pieces according to the invention, it is expedient if their at least two transmission devices are connected to a common integrated circuit. This is preferably able to distinguish between the at least two connection pieces and / or to send specific different connection identifiers for the two connection pieces by means of the transmission device. Alternatively, however, it is also possible to provide each connection piece with its own integrated circuit, which is designed to send only one connection identifier, which, however, is also specific and unambiguous for the connection piece.

A medical device according to the invention can be implemented in a wide variety of devices.

The device can be designed, for example, as a delivery unit, which is to be understood as meaning that the device is designed to apply pressure to the fluid. Such a delivery unit can in particular be designed as a pumping device and, as such, be designed with a piston. In particular, however, it can be a peristalsis pump device in which it is provided that a fluid hose is periodically subjected to force from the outside in order to convey the liquid in the hose on. A delivery unit according to the invention with a peristaltic pump is preferably designed for inserting a fluid line according to the invention of the type described.

As will also be explained below, a medical device according to the invention in the form of a conveyor device and in particular a circuit integrated therein is also suitable for taking over a master in data communication with other components connected to the conveyor device. Such a master controls the communication via the transmission devices and sends, for example, control commands or requests for data transmission to the other components.

A device according to the invention can also be designed as a central venous catheter or peripheral venous catheter. Such a catheter forms a thin access to a vein of the patient and is optionally intended for the temporary stay with the patient. Often, such catheters have a plurality of fittings that allow different fluids and fluid mixtures to be delivered simultaneously. A catheter equipped with connectors according to the invention is able to store in its integrated circuit which fluid sources have been connected to it in order to identify potential incompatibilities on the basis of these.

The device can also be designed as a multi-way tap or as a tap bank. Such a multi-way tap or such a tap bank has at least three connecting pieces, which are preferably are all designed as connection pieces according to the invention, and controls the fluid flow in the device to the connection pieces in the position of a rotary and directional valve. A multi-way tap or a tap bank according to the invention preferably senses the position of at least one directional regulating valve and can identify the connected devices by means of its integrated circuit and the connection pieces according to the invention and record its valve position and connection and pass them on via the connection pieces according to the invention, in particular to one or more Masters, which are preferably formed by the conveyor systems described.

The device can also be designed as a hemodialysis cartridge, a hemodia filter cartridge, a hemofilter or a hemoconcentrator cartridge. In the context of this disclosure, these units are referred to under the term dialysis cartridge.

The device can also be designed as an additional port device and as such has a fluid line provided with a connecting piece on both sides, between which an additional port is provided for adding a fluid on a case-by-case basis. Such an additional port offers a temporary connection option, for example for injecting medication via needle or valve-based access ports on the fluid system. The device can monitor this injection port through the continuous energy supply to the device. If the connection piece of the additional port is designed as a connection piece according to the invention, the device can also communicate with these injection devices, for example with a syringe with a connection piece according to the invention, and thus, for example, query the type of drug as well as information about the dose and the manufacturer.

The device can also be designed as a filter device.

The device can also be designed as a ventilation tube.

The object of the invention is also achieved by an intelligent medical fluid control and transfer system, which has an access unit for applying a fluid or a fluid mixture to a patient or for removing a fluid from a patient and which has at least one liquid container for providing or receiving the Having fluids. The connection pieces described are also used, which are used on the access unit and / or on the liquid container and / or on fluid lines between the liquid container and the access unit. In addition to the container and the access unit, the system preferably comprises at least one further device of the type described above, which may be a conveyor device, for example.

A system in this sense thus comprises at least the absolutely necessary components for fluid supply or fluid removal, the basis for data and / or energy transmission being created through the use of connection pieces according to the invention, in particular also through the use of fluid lines and / or devices according to the invention.

The system includes, in particular, medical equipment, for example a fluid pump, which has an integrated circuit that can query data from the liquid container or the access unit via the data connection created by the connector.

The medical device can form a master in the system, which is designed for communication with other components or the integrated circuits of other components of the system, for example the liquid container or the access unit. However, the master can also be designed separately from a device according to the invention, that is to say it can not have any directly fluid-carrying components itself.

It can be provided that a system has several masters, for example several infusion pumps, which each control the communication with the respective integrated circuits of the components with respect to the components upstream and / or downstream of them in the liquid path. If a system has several masters, these are preferably connected to one another via a separate network, for example via Ethernet or a fieldbus, in order to exchange data from their respective branches of the system or to coordinate control tasks in the various branches of the system.

In principle, several masters in a system can also take on different tasks in that one master supplies the system with electrical energy, while another master controls the data communication. However, it is preferred if a common master unit is used both to supply power to the other components and to control communication with these other components.

Depending on the type of system, different components or their integrated circuitry can be used as masters. In the case of an infusion system, the master is preferably formed by an infusion pump of the system. In a dialysis system, the master is preferably through a Dialysis machine of the system is formed. In the case of a feeding system, the master is preferably formed by a feeding pump of the system. In a drainage system, the master is preferably formed by a drainage pump of the system. In the case of a ventilation system, the master is preferably formed by a ventilation machine of the system.

Furthermore, it is preferably provided that the system and in particular the master of the system are designed to communicate with a server via a data network, in particular via an intranet or Ethernet. This can be done in particular to query data on an identification code of an integrated circuit. Supplementary information can thus be assigned to such an identification code stored in the integrated circuits of the system, for example an expiration date, a batch number or specification data of the fluid line or of the device in which the integrated circuit is provided.

Communication with a server in order to query or add to the medical record with the patient or hospital information system is also useful. The data query can in particular serve the purpose of comparing the patient care provided by the system with information in the medical record. Adding to the medical record means that the care provided by the system can be automatically documented.

The object of the invention is also achieved by an intelligent medical fluid guidance and transfer system. This system comprises at least one fluid source for providing a medically relevant fluid or fluid mixture and an access unit for applying the medically relevant fluid or fluid mixture into a patient. The system further comprises a connecting conductor system which connects the fluid source and the access unit and is designed to conduct and transfer the medically relevant fluid or fluid mixture from the fluid source to the patient, the connecting conductor system preferably having at least one regulating transfer element.

The intelligent medical fluid guiding and transfer system is preferably equipped with at least one of the components as described above.

The components of the medical fluid guidance and transfer system are at least partially designed to determine and exchange information about their status and to report it to a master. To transmit this information, the connecting line system is designed to transmit and forward this information and / or a power supply for the Provide components of the medical fluid control and transfer system, so that the components of the medical fluid control and transfer system form their own information infrastructure and a network topology of the connecting line system and a fluid flow in the medical fluid control and transfer system can be determined by means of this information infrastructure.

For conveying the medically relevant fluid mixture from the fluid source to the access unit on the patient, a conveying unit for conveying the medically relevant fluid mixture is preferably formed between the fluid source and the access unit. Such a conveyor unit can be, for example, an infusion pump in an infusion system. In a ventilator, the pressure is built up by means of a pump or through the applied medium pressure of the ventilation gases.

In drainage situations for wound secretion and urine, the body's natural fluid production is used to drive the fluid flow. In drainage situations, the fluid flow is reversed; H. the fluid source is located in the patient's body and transports the body secretion into a reservoir located outside the body. The fluid flow can also be supported by a pump, as in the case of a Torah drainage. The advantages of the information infrastructure according to the invention in the fluid control systems and distribution elements also come into play here, since the integrity and topology of the drainage system can be checked by means of this infrastructure. The drainage pump, for example, can act as a master.

In dialysis systems, heart-lung machines or extracorporeal gas exchange systems, the medically relevant fluids or fluid mixtures are driven by pumps or by natural media pressure (blood pressure).

In order to ensure the transmission of information and energy, at least in some and preferably in all fluid-conducting components of the fluid-conducting and transfer system, i.e. Integrated into the connecting conductor system, metallic or polymer conductor tracks. As a result, not only the medically relevant fluid mixtures from a fluid source to an access unit into or out of the patient can take place via the connecting lines, but data, information and / or energy can also be transmitted or transferred between the components of the fluid conduction and transfer system in parallel .

For the purposes of this invention, a fluid or fluid mixture comprises substances that are both gaseous and liquid, as well as suspensions and aerosols. Under a Connection conductor system in the context of the invention are understood to mean infusion tubes, IV catheters, ventilation tubes, connecting tubes and connecting pieces.

The information infrastructure can be used to transport and transfer actuator information and commands for changing the flow topology or information displaying content. The information infrastructure in the fluid control and transfer system according to the invention can also be used within medical devices - e.g. B. infusion pumps, dialysis machines, heart-Lun gene machines - or within the patient, d. H. be located in the access unit.

Components of the fluid control and transfer system that are designed to determine their status and report it to a master are understood as elements that are active in terms of information technology. This means that these elements have electronics through which the identification (type, serial number, unique identifier, lumen identification for a multi-lumen catheter), the status (position of three-way cocks, catheter clamps open, filling level of infusion containers), the properties (Drug in the lumen, manufacturing details) and sensor data from the patient are transmitted. These components can be designed with their own power source. For example, the infusion pump in an infusion system can be operated via a mains connection or by means of a battery. The other components can also have a power source.

Because the components can determine and report their status, the elements of an IV therapy, a dialysis system, a nutritional system, a drainage system, a heart-lung machine, an extracorporeal circulatory system, a system for extracorporeal gas exchange or a ventilation system can be identified. This is B. for each drug the patient-side network topology can be determined. In addition, the connections, multi-way faucets, faucet banks, etc. can be uniquely identified by their type, a serial number or a clearly assigned ID. The advantage is that through the clear identification of the components and thus through the determination of the network topology, for example, pharmaceutical drug intolerance can be identified. If the fluid guidance and transfer system according to the invention is connected to a drug and compatibility database in the form of an infusion system, drug instabilities and precipitations in the infusion system can be recognized and prevented. The same applies to transfusion systems, dialysis systems, feeding systems, drainage systems, heart-lung machines, extracorporeal circulatory systems, systems for extracorporeal gas exchange and ventilation systems. The The network topology identified by the respective system can also be compared with a prescribed therapy topology and give an alarm if there is an incorrect administration of medication or the like.

A further advantage of the fluid conduction and transfer system according to the invention is that the effective physical connections of the fluid conduction and transfer system can be checked and thus the probability of leakage can be reduced. Likewise, the flow rate can be measured in the immediate vicinity of the patient and compared with the parameters of a delivery unit, for example an infusion pump, and checked for plausibility.

The components of the fluid conduction and transfer system each have a coupling device for coupling information in and out and / or for coupling energy. In the context of the present invention, a coupling device is understood to mean a connection point which enables data to be transmitted from one component of the fluid control and transfer system via the connection line system to another component of the fluid control and transfer system or a master transfer.

Such a coupling device or connection is z. B. designed so that the Kompatibili ity to the known Luer system is preserved. The coupling can take place, for example, via a Luer lock on Luer lock or a Luer slip on Luer slip or a Luer slip on Luer lock or via a piercing connection from an infusion container in the form of a bottle or a bag to the connection conductor or via a piercing connection from a port needle to an implemented port, the respective coupling being expanded by electronics that enable the transmission of data and energy. The regulating transfer elements are also coupling devices in the sense of the invention. The same principle is used for the connections in feeding systems, ventilation systems, circulatory support systems, oxygenation systems, dialysis systems and drainage systems, whereby the connection geometries typical for the application are used and a coupling functionality for information and Energy to be expanded. For this purpose, the couplings and / or transfer elements known from the prior art are also expanded with electronics that enable the transmission of data and energy. An extended transfer element with appropriate electronics for coupling energy and information is comparable to a hub, which distributes energy or information signals to several components of the fluid guidance and transfer system and transfers ferments. A transfer element can be formed at various points in the fluid guidance and transfer system, depending on where there is a need to regulate the medically relevant fluid mixture to be applied.

The coupling devices are also understood as nodes in the network topology of the fluid control and transfer system. The signal is processed and / or switched at each node in the network. This enables enumeration of the topology - similar to a USB tree, for example - and routing of data packets to addressable nodes. By means of schematically planned time-shifted queries of individual components (time slot method) or by means of frequency multiplexing methods or the like, on the one hand the energy requirement is reduced and on the other hand the collision of data packets is prevented.

The information transmission and forwarding and / or energy supply between the components of the fluid conduction and transfer system and the connecting line system via the coupling device can be electrically wired in a frequency range greater than 100 kHz. The transmission of energy and data packets takes place in a frequency range that does not collide with the action potential and the latency times of cells or negatively influence them. Frequency ranges that are used for electrosurgery are left out in order to avoid signal interference.

In a further embodiment of the fluid conduction and transfer system according to the invention, it is very advantageous if the connection is made contactless by inductive or capacitive coupling. The connection points of the components communicating with one another are galvanically separated from one another. The physical connection of the components is still made via the Luer system or the respective application-specific, medically appropriate connector. However, the parts to be connected are designed in such a way that the transmission takes place by inductive or capacitive coupling, i.e. H. due to the mutual electromagnetic influence of two or more spatially adjacent electrical circuits.

The information transmission and forwarding and / or energy supply between the components of the fluid conduction and transfer system and the respective connecting lines of the connec tion conductor system can also be carried out from a combination of the types of transmission, electrically leiterge, inductive and capacitive. For all types of transmission, lines of the connecting line system lying next to one another must not interfere with each other, even in complex therapy situations, thanks to their design. Modulated carrier frequencies, similar to common NFC technologies, are therefore used for data and energy transmission. These are chosen appropriately in terms of amplitude and frequency.

In contrast to the information technology active elements, components of the fluid guidance and transfer system, which only transmit information and energy via inductive or capacitive coupling, are understood as information technology passive elements.

In one embodiment of the fluid guide and transfer system according to the invention, the master is formed by the delivery unit, the coupling unit or in a cloud.

The fluid guidance and transfer system according to the invention can have several masters. It is advantageous if each conveyor unit - z. B. an infusion pump, and / or the connecting conductor system and / or transfer elements - is designed to receive data from the system, evaluate it and react accordingly. In infusion systems, for. B. known and common practice that exactly one infusion pump is used for each drug or for each infusion solution. In addition, with its mains or battery operation, the infusion pump offers the advantage of always providing enough energy reserves for communication with the remaining components of the infusion system. The system-related directionality of the infusion pump also provides a clear communication logic, which comprises the following steps: i) Query in the proximal direction as to which drug or which infusion solution is assigned to the pump; using sensor information, which is determined via a corresponding sensor system in the medication container, it is possible to determine the status of the infusion solution such as the level, production details, batches, expiry date and unique ID, ii) query in the distal direction about which transfer elements are present; which IV access, which lumen and which patient is connected to the infusion system. Sensor data such as body temperature and oxygen saturation can be recorded and evaluated. The same applies to the formation of the fluid conduction and transfer system as a transfusion system, dialysis system, nutrition system, drainage system, heart-lung machine, extracorporeal circulatory system, system for extracorporeal gas exchange or ventilation system.

Furthermore, it is advantageous if the master is designed to carry out a unidirectional or bidirectional exchange of information with a patient or hospital information system. This makes it possible for the fluid conduction and transfer system to independently display and request, for example, necessary syringe changes or the expected end of therapy, thereby relieving the medical staff.

In addition to direct data processing for controlling and monitoring infusion, transfusion, dialysis, nutritional, drainage or ventilation therapy, these can also be documented automatically in high quality. This enables full traceability.

With the fluid conduction and transfer system according to the invention, the integrity from the fluid source to the patient can be independently validated by the system. Incorrect connections and drug incompatibilities are recognized and the therapy can be documented completely and reliably without a great deal of staff. The fluid management and transfer system according to the invention can ensure that hospital resources are saved and the quality of patient management is increased, for example by being able to independently report and request the expected end of therapy and necessary syringe changes from the fluid management and transfer system.

Another advantage of the fluid control and transfer system according to the invention is also its modula rer structure. The system can be easily expanded by further conveying units, fluid sources and connec tion conductors in the connecting conductor system, which can be added without difficulty to the network topology and information infrastructure.

According to the invention, a computer program product is also proposed which comprises commands which, when the program is executed by a computer, cause the computer to analyze the network topology of the fluid control and transfer system, to check the integrity of the fluid control and transfer system and for the documentation in a Apply patient record. This computer program product can be operated using a tablet which the doctor or medical staff carries with them. The conception of the operation of the system can be simplified in such a way that it is necessary to carry out z. B. home infusion and chemotherapy is suitable.

In an advantageous application, the medical fluid conduction and transfer system according to the invention is designed as a measuring system with a fluid column between the inside of a patient's body and an extracorporeal measuring system for arterial or venous blood pressure. For the intra-arterial pressure measurement, a column of liquid is placed between an intra-arterial theter in the patient and an extracorporeal pressure measurement system for the transmission of the blood pressure. The information infrastructure according to the invention in the hoses, connecting pieces and three-way taps required for this also allows an automatic integrity check, the detection of incorrect connections and the direct reporting of flushing processes in the system and the measuring unit. This avoids measurement errors during the rinsing cycles or blood sampling from the system, as the master can recognize these events from the dynamic topology (such as the position of three-way valves) and communicate them to the measurement system. This principle also applies to invasive venous pressure measurement.

In summary, the fluid control and transfer system according to the invention represents an information infrastructure in infusion, transfusion, dialysis, nutritional, drainage and ventilation therapy, which makes it possible to independently validate the integrity of the fluid source to the patient To recognize incorrect connections and drug incompatibilities and to document the therapy in a validated manner. This is why it is also known as an intelligent fluid conduction and transfer system. The system according to the invention offers full connectivity, with largely no physical contact surfaces being required. This means that the system can also be ideally sterilized and there are no new biocompatibility problems, since contact with the drugs continues to take place via the glass and polymer materials that have been tried and tested for this purpose. In addition, the system is fully backwards compatible through integration into the Luer standard and offers itself as a medium-term industry standard for "smart fluid conduction and transfer system technology".

DETAILED DESCRIPTION OF THE EXEMPLARY EMBODIMENTS

FIG. 1 shows the schematic representation of a network topology of the fluid control and transfer system 10 according to the invention in the configuration of an infusion system. In contrast to known infusion system topologies, the fluid lines 400 between the components 700, 500, 580, 560, 520 of the system 10 and the fluid-carrying components 700, 500, 580, 560, 520 themselves have metallic or polymeric conductor tracks 250 that allow it enable data / information and / or energy to be forwarded and exchanged. The components of the infusion system 10 are each provided with electronics, so that the individual components - such as the transfer elements 560, 580 (e.g. three-way taps 560 or a tap bank 580) or fluid sources 700 (such as infusion bags) or delivery units 500 (like infusion pumps) - are able to identify themselves and determine and report their status.

The intelligent infusion system 10 allows, for example, the functionality to detect faulty connections in the infusion system. The overall system can determine its topology by means of computer code integrated according to the invention and thus determine a deviation of the prescribed medication and the medically prescribed therapy scheme from the actual topology of the infusion system. This review excludes the association of a drug a fluid source 700 to the correct patient 20. Since the patient-side components of the infusion system - including the central venous catheter 520 - are implanted in the patient 20, they allow an unambiguous identification of the patient 20 and thus the check whether a medication or an infusion solution from a fluid source 700 - ie an infusion bag or an infusion bottle - is administered to the correct patient 20.

The intelligent infusion system 10 allows, for example, the functionality to recognize incompatibilities between drugs or between drugs and infusion solutions at the point in the infusion system 10 where the fluid flows meet. To do this, the computer program accesses compatibility databases and compares the infusion topology found with these databases.

FIG. 2 shows the fluid conduction and transfer system according to the invention in the form of a dialysis system 12. In this case, an equitopological information infrastructure is integrated into all components of the blood flow - i. H. from the venous access 550 into the dialysis system 12 with the blood pump 500, the blood line 400 to the blood pump 500 and dialysis cartridge 600, the respective connectors (not shown) and the dialysis cartridge 600 as well as the return flow from blood line 400 to the patient, the air trap 690 and the venous Access 552 - integrated to the patient. An information infrastructure is also integrated in all components of the dialysis system 12, such as the dialysis solution 680 with the dialysis line 400 leading to the dialysis cartridge 600, the dialysate container 670 with the dialysate line 400. The connections between the components are implemented as in FIG. 2, for example. This enables the integrity of these connections to the patient and within the dialysis machine to be verified and incorrect connections to be recognized. The blood pump 500, for example, can serve as a master 800 and as an energy supply and information interface.

3 shows the fluid conduction and transfer system according to the invention in the form of a wound drainage system 14. This has a fluid line 400 which is guided into the body of the patient 20. This fluid line shown above in the figure is connected to a second fluid line 400 which is connected to a unit comprising secretion canister 672 and suction pump 500. The suction pump 500 generates a negative pressure in the secretion canister 672, as a result of which liquid is sucked out of the patient's body through the fluid lines 400.

The two fluid lines 400 are designed as fluid lines according to the invention and therefore have connecting pieces 105 and 106, which not only connect their fluid channel, but also the Conductor 250 provided on both fluid lines 400. On the patient's side, the conductor 250 leads to the distal end of the fluid line 400 ending in the body of the patient 20. A sensor 180 is provided here, which can detect body data of the patient 20. An integrated circuit 170 of the suction pump 500 is connected to the sensor 180 via the conductors 250 and via the connectors 100 and can thus query the body data and, if necessary, store them in a patient file via a network connection (not shown).

FIG. 4 shows the fluid conduction and transfer system according to the invention in the form of a ventilation system 16. The conductors 250 in the ventilation tubes - such as the inhalation limb 400, the exhalation limb 400 - provide an additional check for correct connections, i.e. the correct topology Installation of humidifiers 650, filters 640 and liquid traps 660. The connections of the information infrastructure can, for example, be implemented inductively in accordance with FIGS. 12 and 13, adapted to the geometry of the connection standards in the ventilation system. Sensor data from the ventilation machine 710 or the tube 610 can be transmitted via the information infrastructure 250 without additional cables. The ventilation machine 710, for example, can serve as a master 800 and as an energy supply and information interface.

FIG. 5 shows a simple Luer lock according to ISO 80369-7, which realizes a standardized mechanical connection between a first and a second connection piece 100, 101 of the connecting conductor system. The fluid guidance and transfer system according to the invention maintains the mechanical compatibility with the Luer system, which closes or opens the connection of two parts by half a turn. By integrating a circuit (IC) 170 with a receiver coil 200, 202 in at least one first connector 100, 101 of the Luer lock connection and a further coil 200, 202 in a second connector 100, 101 of the Luer lock connection Both data and energy can be transmitted. Such connectors are used in the infusion system 10 according to FIG. 1.

The connection pieces of the following FIGS. 6A to 8C are preferably also Luer-Lock connection pieces according to ISO 80369-7. However, they can also be other fittings according to the ISO 80369 family of standards.

Figures 6A to 6C show three versions of a connection of two connectors 100, 101 with planar transmission devices 202, 204, 206, 207, 302, 304, 306, 307. The connection pieces 100, 101 of FIG. 6A correspond to the design of FIG. 5 with regard to the essential features. Two fluid lines 400 each have a connection piece 100, 101 at their end, which is attached to the hose body 410 and each via a line section 110 has, which is penetrated by a fluid channel 111. The connection piece 100, 101 on the right in FIGS. 6A to 6C is female and the left connection piece 100, 101 is male. This means that the line section 110 of the left connection piece 100, 101 is pushed into the line section 110 of the right connection piece 100, 101. The line sections 110 are conical in order to create a secure fluid connection.

In addition to the fluid communication through the line section 110, the connection pieces 100, 101 are arranged by the coils 202, 302 already described for FIG.

In the design according to FIG. 6B, two disk-shaped concentric electrode elements 204, 304 for capacitive coupling in a circumferential collar 120 are provided in each of the two connecting pieces. This enables bidirectional communication between the connection pieces 100, for example.

In the design according to FIG. 6C, disc-shaped circumferential contact surfaces 207 are provided on the side of the right connection piece 100, 101. Corresponding sliding contacts 206 are arranged on the left connection piece.

7A to 7C also show connecting pieces 100, 101 with conical line sections 110. However, here the elements for data or energy transmission, that is, the coils 202, 302, the contact surfaces 206, 306, 207, 307 or the electrode elements 204, 304 are not planar det, but roughly ring-shaped or sleeve-shaped. They are integrated on or in walls of the line sections 120. This means that reliable transmission is possible even with very different insertion depths, as is possible with conical connections. Another advantage resulting from the use of the line sections as a carrier for the transmission devices is that rotatable coupling means such as union nuts can be used, the rotatability of which would make it structurally difficult to use a collar according to FIGS. 6A to 6C for attaching the transmission devices to use. 8A to 8C again show connecting pieces 100, 101 with coils, contact surfaces or electrodes that are ring-shaped or sleeve-shaped. However, the corresponding elements are provided here on the one hand in the area of an outside of a coupling section 140 or on the other hand on a jacket wall 150 enveloping the coupling section.

FIG. 9A shows a connection between an infusion bag 700 or an infusion bottle and an infusion tube 400 with extended electronics. In the infusion bag 700 or its connector 100 formed by the crimp cap 100,102B according to ISO 8536-3, a circuit (IC) 170 with a receiver coil 202 is integrated, with a connector 103 according to ISO 8536-4 with another coil in the infusion tube 400 to be attached 202, so that both components - if they were connected to each other - are inductively coupled with respect to information and energy. In this way, data and energy can be transmitted and exchanged via the integrated data line 250 in the infusion tube 400.
